Can't remove Windows partition (disk verified)

I'm using MBPR late 2013. I would like to remove the Win 7 and adjust more space for Win 8.1, so I need to remove and recreate the Win partition.
When I tried to remove the Win partition in Boot Camp Assistant, it shows no error but the process is failed. I also tried to Google the same problem with solution, but the different is my disk is verified with no error (in OS and recovery's Disk Utility). So anyone know what can I do? Thanks.

Because once you use Disk Utility to do any repartitioning after creating the BC partition, then BCA cannot manage the disk any more. Too bad you did not first read the BC documentation that you can print out from BCA.
What you need to do:
Drive Preparation
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

Message: we can't remove windows accounts

We have installed Office 2013 Pro Plus via our E3 O365 subscription. It automatically connects the components (Word, Excel, ...) to the domain user account [email protected] in
our case.
We want to get rid of that account and connect Word, etc to the O365 account of each user.
It turns out that we misspelled the name of a new user in Active Directory. We corrected the error in the name in AD, but the name still has the error in Word, and other Office programs. Where can we correct the name or how can we get rid of this account and
change it in the O365 account?
We can setup a connection to the O365 account but everytime an old document (= created/opened earlier with a connection to the .local account) is opened it hooks up to the .local (domain account).
We can not sign out of the .local account, then we get "We can't remove Windows accounts"
A solution is really appreciated.!

Failed boot camp install - how to remove windows partition?

Hi There,
After a failed boot camp install, boot camp no longer sees (or can remove) a windows partition - Disk Utility can't seem to remove it and if I use:
$ diskutil list
It shows up as partition 5 "Microsoft Reserved"
I also have a portion of free space that I can't seem to incorporate back into the main OSX partition - how do I remove the windows partition and make the drive a single OSX drive again?
Any help would be much appreciated
Cheers
Ben
- New Mac Pro
- Installing onto internal 1 TB SSD
- 10.9.3
- Windows 8.1

Just incase others have this issue, this wasn't caused by using Disk Utility (Disk Utility couldn't remove the partition anyway) it was caused by repeatedly trying to format the Boot Camp partition using the Windows installer when Windows refused to install.
The solution is an Apple tech note (I can no longer find it sorry) that sates that no other hard drives besides the internal HD and the Windows USB flash drive can be connected while installing windows.
Cheers

Thanks Old Comm Guy, BD Aquam and Texas Mac Man for youradvice and reply to my question
and problem with my Zip Drive. However:
    1. Depressing mouse buttonon start up did not eject the zip disk.
    2. To examine front of zipdrive, I had to remove many screws and several plastic case
         coverings. Upon doing thatI discovered that, unfortunately, there is no whole in front
          of mybuilt-in zip hardware drive for me to insert a paper clip to manually eject zipdisk.
      3. I went to the Utilities folder in myMac OS X Application folder, but I could not find
           theiomega zip drive in there.
Also, I did go into my "9" System folder and thento the Extensions folder within it and did find an icon of an
Iomega Driver. When double clicking on it a window came upstating I was opening the application
"ColorSync Extension" for thefirst time, and asking if I was sure I wanted to open this application.
Uponclicking open nothing happened - nothing opened.
I also went into the "System X" folder>Libraryfolder>Extension folder>IomegaSAM.ket icon and double
clicked on it and asmall window opened stating "Compiling file List", however nothingopened it just
continued to compile, so I closed it.
Within my Mac OS X HD> Applications>Iomega folder>Iomega Tools.app a smallwindow opened up
with several options (Erase, Protect, Disk Info and DriveInfo). Clicking on the Drive Info a message says:
"No Iomega Drives or noIomega Driver found. Therefore, Ihave gone to Mac, Iomega and other websites
trying to find a Driver for thebuilt-in Zip Drive in my Mac G-4 OS X 10.4.11, but have not really found anythat work.
CAN ANYONE TELL ME IF THERE IS A WEBSITE WHERE I CANDOWNLOAD A NEW DRIVER FOR MY ZIP DRIVE?

You are telling us you read and tried the normal methods?
Boot Camp or Taskbar. Option on restart. "x" on startup. And none of those work.

Why can't I recover disc space after removing Windows partition?

Greetings,
I have an early 2008 iMac 3.06 GHz Core 2 Duo with a 500 GB HD that I have steadily updated from Leopard to Mountain Lion. I also had partitioned my HD using Bootcamp 2.0 to run Windows Vista Ultimate 64-bit. Everything hummed along nicely until the upgrade to OS 10.8.2. After that I could no longer start up in the Windows partition, ostensibly due to system registry files having become corrupt (or missing). After several vain attempts at recovering Vista, I determined to start over using Bootcamp (now upgraded to 5.0), but 5.0 would install Windows 7, apparently not Vista. I was able to remove the Windows partition using Bootcamp 5.0 (the Windows drive no longer shows up at start up when I hold down the option key Macintosh HD and Recovery 10.8.2 remain). I was hoping to recover the remaining HD space for the Mac. In Disc Utliity, it shows the Mac HD occupies 337 GB of space (about 86 GB is free). The remaining 162 GB is greyed out. If I resize the Mac HD to take up the remaining space and attempt to repartition it says "Partition Failed -- couldn't modify partition map because file system verification failed".
I would like to recoup as much of the 162 GB as feasible, but at this point neither Bootcamp nor Disc Utility seem to be helping. How can I accomplish this?Thanks.

I have a problem on my early 2011 macbook pro customized with core i5 processor and 500gb hdd regarding BOOTCAMP for Installing Windows 8 on OS 10.9 Mavericks
I tried to install windows 8 with bootcamp on OS X 10.9 Mavericks but while partitioning bootcamp was not responding and then i force quit it. After that i opened disk Utility and it showed no partitions for windows 8.
But then my HDD which had 210GB free later showed as 136.27 Gb free only. IT means that my partition was not successful and it took up 74GB on my HDD.
I dont want to erase my HDD and Reinstall OS X but want a solution to get my 74GB space back on my hdd without troubles of formatting and restoring from backup.
Plz Help Solution Needed Urgently.

Unable to remove windows partition

Hi:
I want to remove my windows/boot camp partition to free up space on my hard disk. When I launch Boot Camp Assistant to accomplish this, it gives me the error message, "The startup disk does not have enough space to be partitioned. You must have at least 10 GB of free space available." Well, thanks for the warning, but I want to REMOVE the partition and thus increase the available space on my startup disk. But Boot Camp Assistant will not allow me to advance futher, and I'm forced to quit. Ideas?

No one has any ideas on this? Is it simply a case of terrible user interface design?
I have attempted to use Disk Utility to accomplish this task. It allowed me to delete the Boot Camp partition from my drive, but will not allow me to expand the Macintosh HD drive to use the entire hard disk. I keep getting the error message "Disk Utility was unable to verify the partition." I suspect this is because it was a Windows-formatted partition.
I have also deleted enough files from my drive so that there are 22 GB available, but Boot Camp Assistant still claims that I have fewer than 10GB available on the disk, and therefore refuses to show me the partition removal screen.
I'd appreciate any help that people might have.
Disk Utility is the wrong tool to use, it can (and will) cause problems. Backup your entire disk, erase and then restore it.

How can I remove Windows XP from my MacBook Pro?

I've tried everything I can find to get rid of Windows XP on my MacBook Pro. I have OS X 10.5.8 and, unlike later versions, BootCamp Assistant 2.0 doesn't allow the option to restore the disk. And I can't find an update to BootCamp anywhere that will work. Seems I need Snow Leopard to upgrade to 3.0.

Boot Camp has an option to remove the Windows partition provided you made the partition with Boot Camp and did not later modify it or create a third-partition on the drive.
This may work:
Open Disk Utility, select your drive in the sidebar, then click on the Partition button in the DU main window. Select the Windows partition by clicking in the Windows rectangle of the partitions display. Click on the Delete [-] button to remove the partition then click on the Apply button. Wait for DU to either complete the operation or error out. If DU removes the partition then click on the partition sizing gadget (lower right hand corner) on the main partition and drag all the way to the bottom to fill the gray space left from removing the Windows partition. Click on the Apply button and wait until the operation is completed.
If you get errors at either of the two procedures then that means the drive's RDB has been damaged or altered. In this case backup the drive, boot from the backup, erase the drive, then restore the backup.

Very Slow Performance After Removing Windows Partition

Hello,
Recently I went through a failed attempt at installing Windows 7 onto my Macbook Pro using boot camp. After this failure I decided to try again another day and used the boot camp assistant to remove the Windows partition.
Ever since doing this, my computer has been running extremely slowly and beach balls on the simplest of tasks. I have tried resetting the SMC and my PRAM all to no avail. I have also used Disk Utility to verify my disk and it says that my disk looks OK.
Has anyone else experienced this/know of any possible fixes?
Thank you for your help!

Hi,
This may happen sometimes due to anti-virus or firewalls also.Disable them and check if it works better...Or, otherwise try these:
- First uninstall the latest Windows Updates.
Click on the Start Button> Type Windows Updates in the Start Search box > Click View Installed Updates at appears at the top > In the Installed Updates screen Sort the updates as per installed date by clicking on the Down arrow next to installed and choose a date or last week...
Uninstall the updates that were installed recently one by one. Do not restart.Click cancel on restart window.
Then perform a clean boot as shown in the link and follow these steps:
Perform a clean boot >
In the start search box type msconfig > Click Startup tab > Click disable all at the bottom > Then Click services > check the box next to Hide all microsoft services at the bottom > Then select disable all > Click Apply > Ok and restart.
Once it restarts then go to windows updates and complete all the updates > Restart and check. If it works better then Go bak to msconfig and enable only the startup programs and services that are required. Enable few and check again..
Let me know if problem continues..
Note:
If you have HP Support Assistant installed on the computer(The Blue Question Mark) then open it ==> Complete all pending Updates & Tuneups==> Restart and Check. It may solve your problem
Although I am an HP employee, I am speaking for myself and not for HP.

Remove Windows partition before or after upgrading to Leopord

Hi,
I have been using boot camp beta for some time. A short time ago, the Windows partition became unusable because the partition was too small. It appears the least risky approach would be to restore the disk to a OS X only system then re-install Windows on a larger partition. I have the Leopard upgrade disk. I have also read article 306805 which involves rolling back the computer clock.
My question is would it be safer to remove the Windows partition before or after upgrading to Leopard?

Backup and reformat your drive with Leopard. Then install both. You can use Migration Assistant to restore your files and settings.

Can't Mount Windows Partition in OSX After Upgrading to 10.5 and BC 2.0

I just installed Leopard today, using the upgrade option (as opposed to a clean install). I was happy to see that I could boot into Windows still, and installed all of the Boot Camp 2.0 drivers while booted into Vista. However, I can no longer mount my Windows partition in OSX. While using Tiger, I did use MacFuse and ntfs-3g to get read-write support, but in Leopard, I can't even read. When I try to mount the Windows volume in Disk Utility, I get an error stating that it cannot be mounted. I also do not have the option to perform "First Aid" or "Repair" on the volume.
I realize that the latest version of ntfs-3g isn't proven to work with Leopard, but I would at least like read access in OSX. Is it possible that some settings were left over from my Tiger configuration that would not allow Leopard to mount the partition? Any ideas?
Thank you.

Ok. I'm in the club with the same problem...
Strange things:
* For the first days after Leopard's install, my BootCamp disk0s3 partition (I'll name it "BillGates") was mounted correctly. Then, after a few days (but BEFORE upgrading to 10.5.1), it disappeared.
* If I launch DiskUtility "BillGates" is shown, but (in the right device navigation bar) it's named "-n BillGates". If I click the Erase menu, it's named "-nBillGates" (without the space between "-n" and "BillGates"). If I launch SystemProfiler it's named "-n BillGates", but the mount point is "/Volumes/billgates". Can't understand where this "-n" thing is coming from!
* If I try to mount "-n BillGates" from DiskUtility it doesn't work and the log says "Mount of -n BillGates failed".
* In the FSTAB there were no instructions: it was empty.
Now, I tried the MacFUSE-solution: no results (meaning BillGates was not mounted on startup).
I tried the modify-the-FSTAB-solution: no results (with "BillGates", "-n BillGates" nor "-nBillGates".
I tried the chkdsk-solution: all tests were ok, but nothing happened.
The only trick that worked was mounting the partition with Terminal's commands (thanks rtracy!!). It made appear "BillGates" on the desktop (without the "-n thing", that is still present in DiskUtility).
Problem is at the first reboot, the Boot Camp partition disappears again. Any ideas for a permanent fix?!
Giangiacomo.
ADDENDUM: I've tried to move a file from desktop to an unlocked folder in BillGates and System did not copy them. "The item could not be moved because "BillGates" cannot be modified" !!!!!!!!
